mbed_official 133:d4dda5c437f0 75 ##### Peripheral extended features functions #####
mbed_official 133:d4dda5c437f0 76 ===============================================================================
mbed_official 133:d4dda5c437f0 77
mbed_official 133:d4dda5c437f0 78 *** Main and Backup Regulators configuration ***
mbed_official 133:d4dda5c437f0 79 ================================================
mbed_official 133:d4dda5c437f0 80 [..]
mbed_official 133:d4dda5c437f0 81 (+) The backup domain includes 4 Kbytes of backup SRAM accessible only from
mbed_official 133:d4dda5c437f0 82 the CPU, and address in 32-bit, 16-bit or 8-bit mode. Its content is
mbed_official 133:d4dda5c437f0 83 retained even in Standby or VBAT mode when the low power backup regulator
mbed_official 133:d4dda5c437f0 84 is enabled. It can be considered as an internal EEPROM when VBAT is
mbed_official 133:d4dda5c437f0 85 always present. You can use the HAL_PWR_EnableBkUpReg() function to
mbed_official 133:d4dda5c437f0 86 enable the low power backup regulator.
mbed_official 133:d4dda5c437f0 87
mbed_official 133:d4dda5c437f0 88 (+) When the backup domain is supplied by VDD (analog switch connected to VDD)
mbed_official 133:d4dda5c437f0 89 the backup SRAM is powered from VDD which replaces the VBAT power supply to
mbed_official 133:d4dda5c437f0 90 save battery life.
mbed_official 133:d4dda5c437f0 91
mbed_official 133:d4dda5c437f0 92 (+) The backup SRAM is not mass erased by a tamper event. It is read
mbed_official 133:d4dda5c437f0 93 protected to prevent confidential data, such as cryptographic private
mbed_official 133:d4dda5c437f0 94 key, from being accessed. The backup SRAM can be erased only through
mbed_official 133:d4dda5c437f0 95 the Flash interface when a protection level change from level 1 to
mbed_official 133:d4dda5c437f0 96 level 0 is requested.
mbed_official 133:d4dda5c437f0 97 -@- Refer to the description of Read protection (RDP) in the Flash
mbed_official 133:d4dda5c437f0 98 programming manual.
mbed_official 133:d4dda5c437f0 99
mbed_official 133:d4dda5c437f0 100 (+) The main internal regulator can be configured to have a tradeoff between
mbed_official 133:d4dda5c437f0 101 performance and power consumption when the device does not operate at
mbed_official 133:d4dda5c437f0 102 the maximum frequency. This is done through __HAL_PWR_MAINREGULATORMODE_CONFIG()
mbed_official 133:d4dda5c437f0 103 macro which configure VOS bit in PWR_CR register
mbed_official 133:d4dda5c437f0 104
mbed_official 133:d4dda5c437f0 105 Refer to the product datasheets for more details.
mbed_official 133:d4dda5c437f0 106
mbed_official 133:d4dda5c437f0 107 *** FLASH Power Down configuration ****
mbed_official 133:d4dda5c437f0 108 =======================================
mbed_official 133:d4dda5c437f0 109 [..]
mbed_official 133:d4dda5c437f0 110 (+) By setting the FPDS bit in the PWR_CR register by using the
mbed_official 133:d4dda5c437f0 111 HAL_PWR_EnableFlashPowerDown() function, the Flash memory also enters power
mbed_official 133:d4dda5c437f0 112 down mode when the device enters Stop mode. When the Flash memory
mbed_official 133:d4dda5c437f0 113 is in power down mode, an additional startup delay is incurred when
mbed_official 133:d4dda5c437f0 114 waking up from Stop mode.
mbed_official 133:d4dda5c437f0 115
mbed_official 133:d4dda5c437f0 116 (+) For STM32F42xxx/43xxx Devices, the scale can be modified only when the PLL
mbed_official 133:d4dda5c437f0 117 is OFF and the HSI or HSE clock source is selected as system clock.
mbed_official 133:d4dda5c437f0 118 The new value programmed is active only when the PLL is ON.
mbed_official 133:d4dda5c437f0 119 When the PLL is OFF, the voltage scale 3 is automatically selected.
mbed_official 133:d4dda5c437f0 120 Refer to the datasheets for more details.
mbed_official 133:d4dda5c437f0 121
mbed_official 133:d4dda5c437f0 122 *** Over-Drive and Under-Drive configuration ****
mbed_official 133:d4dda5c437f0 123 =================================================
mbed_official 133:d4dda5c437f0 124 [..]
mbed_official 133:d4dda5c437f0 125 (+) For STM32F42xxx/43xxx Devices, in Run mode: the main regulator has
mbed_official 133:d4dda5c437f0 126 2 operating modes available:
mbed_official 133:d4dda5c437f0 127 (++) Normal mode: The CPU and core logic operate at maximum frequency at a given
mbed_official 133:d4dda5c437f0 128 voltage scaling (scale 1, scale 2 or scale 3)
mbed_official 133:d4dda5c437f0 129 (++) Over-drive mode: This mode allows the CPU and the core logic to operate at a
mbed_official 133:d4dda5c437f0 130 higher frequency than the normal mode for a given voltage scaling (scale 1,
mbed_official 133:d4dda5c437f0 131 scale 2 or scale 3). This mode is enabled through HAL_PWREx_EnableOverDrive() function and
mbed_official 133:d4dda5c437f0 132 disabled by HAL_PWREx_DisableOverDrive() function, to enter or exit from Over-drive mode please follow
mbed_official 133:d4dda5c437f0 133 the sequence described in Reference manual.
mbed_official 133:d4dda5c437f0 134
mbed_official 133:d4dda5c437f0 135 (+) For STM32F42xxx/43xxx Devices, in Stop mode: the main regulator or low power regulator
mbed_official 133:d4dda5c437f0 136 supplies a low power voltage to the 1.2V domain, thus preserving the content of registers
mbed_official 133:d4dda5c437f0 137 and internal SRAM. 2 operating modes are available:
mbed_official 133:d4dda5c437f0 138 (++) Normal mode: the 1.2V domain is preserved in nominal leakage mode. This mode is only
mbed_official 133:d4dda5c437f0 139 available when the main regulator or the low power regulator is used in Scale 3 or
mbed_official 133:d4dda5c437f0 140 low voltage mode.
mbed_official 133:d4dda5c437f0 141 (++) Under-drive mode: the 1.2V domain is preserved in reduced leakage mode. This mode is only
mbed_official 133:d4dda5c437f0 142 available when the main regulator or the low power regulator is in low voltage mode.
